I am a big lover of capsule wardrobes and love the S&B board.
I have some more expensive items (only talking expensive high street not designer) in my capsule that work hard - but I heard good advice a while ago that basically said it doesn't matter if something comes from Primark as long as you treat it as though it is an investment and it earns its keep. I have a Primark navy shirt that must be 10 years old and I wear it once a week at least. I also have a F&F simple black top that was passed on from a friend - I know she paid £12 for it. Likewise, I have had it years and wear and wash once a week and it's perfect. Anyone got similar very cheap items that have been workhorse pieces for them?
oops! and I forgot my lovely silk paisley shirt that was a pound in a charity shop- brand unknown but I think it might be Next.
